Title: Innovations of Hongchun Cong in Gray Scale Measurement
Introduction
Hongchun Cong is a notable inventor based in Shaanxi, China. He has made significant contributions to the field of image processing, particularly in gray scale measurement technologies. With a total of three patents to his name, Cong's work has advanced the capabilities of light-emitting diode (LED) displays.
Latest Patents
Cong's latest patents include a "Method for gray scale measurement, non-transitory storage medium, and processor." This invention provides a method and apparatus for gray scale measurement. The method involves collecting a first part of gray scale data from an LED screen while displaying an image, determining the type of chip used to drive the LED screen, and predicting a second part of gray scale data based on the chip type and the first part of gray scale data. Another significant patent is the "Image adjustment device and image adjustment method suitable for light-emitting diode display." This method generates a grayscale value of a target pixel by weighted averaging multiple input sub-pixel data. It calculates foreground and background values to obtain a just-noticeable difference value, which is then used to generate an adjusted grayscale value for the target pixel.
